WINDING-ARBOR FOR STEM-WINDING WATCHES.

SPECIFICATION Iormmg' art of Letters Fatent No. 225,220, dated March 9,1880.

Application filed J annar 26, 1880- To all whom it may concern:

Be it known that I, ILLIAM P. HILLICK, of Fulton, in the county ofOswego and State of New York, have invented a new and useful Improvementin Steam-Windin Watches, of which the following is a specification,reference being had to the annexed drawings, in whichv Figure 1represents a longitudinal section. Fig. 2 represents a top-plan view ofthe arbor. Fig. 3 represents a cross-section on line .12.

My invention consists of a new pnslrpin and winding-arbor so constructedas to be readily adapted to the different styles of stemwinding watches,some of which are made with simply a socket to receive the windingarborand others with a fixed arbor.

1 am aware that push-pins with arbors attached rigidly to them, or madeall in one piece, have been heretofore used; but the use of such islimited to watches made with a socket to receive the arbor;

A is the push-pin, titted in any ordinary manner into the hub in thehead-piece 15. It is made round, with a groove, in, around it, toreceive the inner end. of the stemscrew which holds the push-pin inplace.

The other end of the pin A is made with a square socket, U, of anydesired depth. A screwthroaded hole is niade near this end of thepush-pin, into which the set-screw o is fitted. This hole should be nearthe center of one of the square sides of the socket 0. This socketdesigned to receive one end of the removable winding arbor 1). Thiswinding-arbor is made of a square piece of metal of proper length, andof such size as to fit into the socket U. Across one side of this arbor,near the inner end, a transverse groove or slot is out about one-haltway through.

The outer end of tho arbor is beveled ofi' slightly. The transverse slota is so located that when the arbor is inserted in the socket G the slotwill receive the point of the setscrcw 0, which, when screwed down,willhold the arbor in place in the socket and prevent its beingwithdrawn. This slot to is made wider than just what is needed to simplyreceive the end of the set-screw, because the case-spring of ahuntingavatch is usually operated to open the case by pressure upon thepuslrpin; and to allow this endwise movement of the push-pinindependentof the an her this slot is widened.

, In a watolrinadc with a socket to receive the arbor the whole of mypush-pin and winding-arbor is used, being inserted through the usualhole in the stem of the case, the arbor fitting into the socket in themovement, and the whole held in place by a set-screw through the stem inthe usual manner, fitting into slot at; and in a watch made with afixed'winding-arbor I remove my removable arbor and insert the socketedpush-pin, the fixed arbor fitting into the socket O. I

In this manner my push-pin and removable winding-arbor can, at pleasure,be used in either style of stem-winding watches, and a jeweler is onlyobliged to keep on hand one kind of cases, while a different style ofcase is now required for each of the two kinds of stem-windingmovements.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The above-described push -'pin A, constructed with the socket G inits inner end, and provided with the set-screw 0, extending into thesocket, substantially as set forth.

3. In a stein-winding watch, the removable wimling-arbor l), fittinginto the socket G in the push-pin A, and provided with a transverseslot, a, made wider than the point of the set-screw o to allow the cndwisc movement of the push-pin independent of the arbor, constructed asabove described.

3. In a stein-winding watch, the combination, with the windingmechanism, of the pushpin A, with the socket U in its lower end, andprovided with a set-screw, o, and the 1'c1 novable winding-arbor D,constructed to fit at one end into the socket G and at the other. intothe winding mechanism, and provided with the slot (0 to receive theset-screw 0, when constructed and operating together substantially asabove specified.

In. witness whereof hand.

I have hereunto set my W. 1. HILLIGK. In presence of- U. W. Snrrn,U-nonen BEADLE.
